Please not same old drama again, what you see in one grid is in 1000 opensim grids one DMCA notification is US$ 6 x 1000 = US$6000 you are not a record label you don't have that kind of money quit drama and get real when something is removed everybody uploads again then you have 100 duplicates with different UUID's in all grids again, are you some kind of noob in Opensim?

Best advise i can give is protect your business before kinggons come and turn all those years of work into public domain stuff, these days only talented people like you are copyboted, your business is protected in SL, what you see in opensim grids is the price of your fame , survival rule #1 in the jungle you can't make much noise. Get foucos in your source of incoming, not with what give you nothing in return but headaches. BTW everybody backups in opensim and there are many more grids then statistics say, now any user can be a grid owner in less than 30 mins.
